For three quarters on Saturday, Washington's defense did all it could to keep the Huskies in their College Football Playoff semifinal against No. 1 Alabama. But then Bo Scarbrough set it all on fire with one unbelievable run.

Leading 17-7 early in the fourth quarter, the Crimson Tide faced a second-and-9 at their own 32-yard line when quarterback Jalen Hurts handed off to Scarbrough, and the 6-foot-2, 228-pound sophomore provided the highlight of the game with this electric 68-yard touchdown run:

All that, despite being wrapped up behind the line of scrimmage before breaking it open. No fewer than seven Washington players had a legitimate shot to make some attempt to stop him during the run, to no avail.

That drive started at Alabama's own 2 after Washington quarterback Jake Browning -- yep -- executed a beautiful punt that rolled out of bounds just before the goal line. But it took the Tide just six plays to score. Scarbrough also had another 12-yard run earlier in the drive and was over 175 yards for the game with two touchdowns.

Alabama added the extra point to go up 24-7 with 11:56 to go, and time is running out on the Huskies.
